Aim Sequencing technology has replaced conventional methods in identifying and characterizing bacterial pathogens. We characterized 23 nonserotypeable Shigella that biochemically resembled Shigella spp. using whole genome sequencing. Materials & methods Genome sequences were analyzed using online tools based on 16S rRNA, k-mer, gyrB sequences and analysis of O-antigen arrangement was done usi...

The Shigella bacteria cause bacillary dysentery, which remains a significant threat to public health. The genus status and species classification appear no longer valid, as compelling evidence indicates that Shigella, as well as enteroinvasive Escherichia coli, are derived from multiple origins of E.coli and form a single pathovar. Nevertheless, Shigella dysenteriae serotype 1 causes deadly epi...

BACKGROUND Antimicrobial resistance has been inflecting deleterious health and economic consequences locally and globally. This study addresses the patterns and trends of bacterial resistance to antimicrobial agents over a decade, at a major tertiary care center in Beirut. METHODS Data on bacterial susceptibility patterns at the CAP accredited Clinical Microbiology Laboratory is analyzed from...

Seventy polyfloral honeys including commercial samples obtained from supermarkets, harvested from apiaries and purchased in bulk were initially examined for total antibacterial activity. From each sample, numbers of aerobic mesophilic bacteria, total coliforms, moulds and yeasts were determined and the presence of Salmonella spp., Shigella spp., Clostridium sulfite-reducers, Paenibacillus larva...

This study was conducted to assess the bacteriological quality of alternative drinking water supply options in southwest coastal areas of Bangladesh. A total of 90 water samples were collected during both dry and wet seasons from household based rainwater harvesting systems (RWHSS), community based rain water harvesting systems (CRWHSs), pond-sand filters (PSFs) and ponds. The samples were eval...

Shigella flexneri is a Gram-negative facultatively intracellular pathogen responsible for bacillary dysentery in humans. More than one million deaths occur yearly due to infections with Shigella spp. and the victims are mostly children of the developing world. The pathogenesis of Shigella centres on the ability of this organism to invade the colonic epithelium where it induces severe mucosal in...

The in vitro activities of temafloxacin (A63004) and lomefloxacin (SC-47111; NY-198) were compared with those of seven other antibiotics against 146 isolates of bacterial enteric pathogens, including Campylobacter jejuni and Campylobacter coli. Ciprofloxacin was the most active drug against the Salmonella, Shigella, Yersinia, and Vibrio spp. tested. Lomefloxacin, temafloxacin, and difloxacin we...

A two month study to investigate the incidence of nosocomial infection was conducted in a paediatric gastroenteritis ward of a black academic hospital. Enteric pathogens were identified on admission in 61 (47.2%) of 129 patients; 56 bacterial and 25 viral. Six per cent of patients had a combination of bacterial and viral pathogens. Enteric pathogens most frequently identified on admission were ...

This is a correction of an earlier published article. Text After the publication of this work[1], we became aware that the our description of the methods used to identify Shigella spp. did not describe the identification of a subset of Shigella spp. which were untypeable with commercial sera. Additional typing was conducted by Dr. Kaisar A. Published: 26 January 2007 BMC Infectious Diseases 200...
